White Paper Abstract:
One would have to be a hermit not to have been exposed to the hype associated with an approach to IT application design and construction known as Service-Oriented Architecture, or simply SOA. One is just as likely to be confused by the seemingly universal application of this term to every vendor’s latest products, especially those that complement and used worldwide Web technology and infrastructure. Just to set the stage and, hopefully, separate this from some of the less content-rich marketing documents on this topic, let’s start by defining what we are talking about. In its reference model for SOA, the Organization for the Advancement of Structured Information Standards (OASIS) defines
SOA to be “... a paradigm for organizing and utilizing distributed capabilities that may be under the control of different ownership domains.” This definition seems to be very broad and unhelpful, until you examine it in detail.
